Accompanying drawing explanation
Fig. 1 is the schematic diagram that traditional wind turbine gearbox guides axle sealing structure；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
Shown in Figure 2, wind turbine gearbox of the present utility model guides axle sealing structure, including O RunddichtringO 11, it is supported in the bearing 12 in the endoporus of second level power shaft end cap 6, left end is connected with leading axle upwind end cap 2, the leading axle main body 1 that right-hand member is connected with leading axle sleeve pipe 4, described leading axle upwind end cap 2 is assemblied on planet carrier 3, the right side of described leading axle sleeve pipe 4 is assemblied under leading axle on wind direction end cap 5, under described leading axle, the left end of wind direction end cap 5 is connected with the right-hand member of second level power shaft end cap 6, described second level power shaft end cap 6 is assemblied on back box lid 7, described bearing 12 is supported in the endoporus of second level power shaft end cap 6.From Figure 2 it can be seen that described O RunddichtringO 11 is assemblied between periphery and the endoporus of planet carrier 3 of leading axle upwind end cap 2 hermetically.Therefore, as long as O RunddichtringO 11 being first assemblied on the periphery of leading axle upwind end cap 2, leading axle upwind end cap 2 is installed on the periphery of planet carrier 3 endoporus and leading axle main body 1 the most simultaneously, just O RunddichtringO 11 is assemblied in hermetically between the periphery of leading axle upwind end cap 2 and planet carrier 3 endoporus.Then, will not be by O RunddichtringO 11 scratch during assembling so that it is sealing effectiveness is guaranteed, thus safety and reliability is higher.
From Figure 2 it can be seen that be provided with ring-type O RunddichtringO 14 between the endoporus and the periphery of leading axle sleeve pipe 4 of described leading axle main body 1.This makes sealing effectiveness of the present utility model more preferable, and safety and reliability is more preferable.
From Figure 2 it can be seen that this utility model also includes bearings sleeve 8, described bearings sleeve 8 radially loading is assigned between leading axle main body 1 and bearing 12 and right-hand member is detachably connected with the left end of leading axle sleeve pipe 4.So, when ring-type O RunddichtringO 14 needed after losing efficacy to change, wind direction end cap 5 under leading axle, leading axle sleeve pipe 4 and bearings sleeve 8 can be pulled down more easily, ring-type O RunddichtringO 14 after losing efficacy is replaced maintenance, and the repair and replacement making ring-type O RunddichtringO 14 are more convenient easily.
From Figure 2 it can be seen that be provided with contactless labyrinth sealing 13 under described leading axle sleeve pipe 4 and leading axle between wind direction end cap 5.This makes sealing effectiveness of the present utility model be guaranteed further, thus safety and reliability is also further enhanced.
From Figure 2 it can be seen that be provided with annular end face O RunddichtringO 15 between left side and the right side of second level power shaft end cap 6 of wind direction end cap 5 under described leading axle.This makes sealing effectiveness of the present utility model more preferable, thus safety and reliability is more preferable.
From Figure 2 it can be seen that be provided with drainback passage 16 between described contactless labyrinth sealing 13 and leading axle sleeve pipe 4.Lubricating oil so can be made to pass through drainback passage 16 flow out between contactless labyrinth sealing 13 and leading axle sleeve pipe 4, it is to avoid pile up more and more in this place, affect sealing effectiveness.
From Figure 2 it can be seen that also include skeleton sealing 9, described skeleton sealing 9 is assemblied under the periphery of leading axle sleeve pipe 4 and leading axle between the endoporus of wind direction end cap 5 right-hand member.So it is prevented from lubricating oil outwards to leak out between the endoporus of wind direction end cap 5 right-hand member from the periphery of leading axle sleeve pipe 4 and leading axle, makes sealing effectiveness of the present utility model more preferable.
